    Abstract: A single machine combines both a high-speed magnetic tape duplication apparatus and a casette loader (60). The duplicator may accommodate either anhysteretic or thermo-magnetic transfer, and the master tape transport mechanism may function either in a shuttle or a bin-loop mode. In an alternative embodiment of the invention, a single master tape (2) is threaded through multiple transfer heads (28, 30), each head being fed from a separate pancake-type copy-tape supply reel (18a, 18b) and routed into dedicated cassette loading stations (60) to enhance system throughput.

    Abstract: Open spool reels (18) of magnetic tape (7) are recorded with a plurality of different programmes interspersed with recordings in a different form (typically as interruptions to the sync track), representing data information concerning the programme material and production history of the recording. The data (6) recorded on the tape (7) is read by a transducer (39) on a cassette loading machine (30) and used to control the operation of the loading machine, identifying the length of tape and the position on the tape where splices between the magnetic tape (7) and leader tape in cassette shells is to be made. The data (6) also controls a label printer (46) to produce a printed label, typically in bar code form, carrying information representing the programme material on the tape loaded into the cassette. This label is automatically applied to the cassette shell as part of the cassette loading operation so that each cassette is securely provided with external easily read information identifying the programme content thereby avoiding the necessity for individual playback of a tape to identify its programme content.

    Abstract: A master disk for simultaneous recording of all information upon a thermo-magnetic recording disk, has a layer of a heating-energy-reflecting material supported by a substrate of a material substantially transparent to the form of heating energy used. The reflecting material layer is apertured at locations at which the disk-to-be-recorded is to have a bit of digital information of opposite binary value from the binary value of locations at which the reflecting layer remains intact. The master disk is placed adjacent to a recording disk previously having all domains therein magnetized in a first direction, and a beam of heating energy, such as light and the like, is directed through the master disk, in the presence of a magnetic field of direction opposite to the direction of the previous magnetization of the domains. The magnetization of domains situated under apertures in the reflecting layer is reversed, responsive to the heating energy beam and the opposite-direction external field, to rapidly write the binary information from the master disk onto the recording disk.

    Abstract: Apparatus is provided for selectively transferring data from one to another of a plurality of display registers. Selector switches (52, 56, 60, 82, 86, 90, 120, 128) are associated with respective ones of the display registers (50, 54, 58, 80, 84, 88, 120, 128, 144), each selector switch being manually operable so as to be designated either as a source switch or as a destination switch, whereby the data in the display register associated with the source switch is transferred to the display register associated with the destination switch. A central processing unit (not shown in Figure 1) is responsive to the operation of a first of the selector switches followed by the operation of a second of the selector switches to transfer the data from the display register associated with the first selector switch to the display register associated with the second selector switch. Preferably, indicators are associated with respective ones of the selector switches; and the central processing unit controls the indicator associated with the first-operated selector switch to provide a distinctive indication representing that this selector switch has been designated as the source switch. A desired application of this invention is in video editing apparatus that is used with video playback and recording devices in which video information that is reproduced from one device is recorded on the other. In such an application, the data in the respective display registers is position data representing relative positions of the record media of the playback and recording devices. Such display registers constitute a present position register for displaying the present position of one of the record media, a "start" register for displaying the position at which the start of an edit operation is to commence, and a "stop" register for displaying the position at which the edit operation is to end.

    Abstract: This method produces a tape (10) having a plurality of recorded segments having a reduced tendency to generate errant control track pulses. The method includes applying a layer of a liquid dispersion to a nonmagnetic substrate. The method also includes the steps of orienting the pigment by applying a magnetic field, solidifying the layer of liquid dispersion on the substrate, and applying a demagnetizing field to the layer to neutralize the remanent magnetization.

    Abstract: A method for synchronously operating two or more rotary head digital audio tape recorders without having to dedicate a separate timing track. The present invention synchronizes the machines in three steps. First, the slave unit reads the time code (111) value from the data stream and compares this time code (111) to the master's time code (111) examining the difference in time code (111) values and adjusting the transport speed so that the values are approximately equal. Next, the slave's capstan motors are slowed down (or sped up) so that the slave and master units are within one drum revolution of each other. Finally, the slave's microprocessor adjusts the speed of the entire system to skip individual samples until the master and slave units are synchronized.

    Abstract: A method of producing many duplicate magnetic disks from a master disk at high speed using a simple device while preventing the demagnetization of the master disk. The disk for duplication has a magnetic layer including magnetic powder such as hexagonal ferrite crystals, a majority of which has the easy axis substantially perpendicular to the disk surface rather than along the tracks. The disk is placed in a manner that its magnetic layer is in contact with the magnetic layer of the master disk in which signals are recorded with magnetization along the tracks. The alternating magnetic field is applied over the disks in nearly a vertical direction, so that the signals of the master disk are transferred to the disk for duplication.
